• Rails: periodically use HEAD to check for page changes

  - by Chris

  I have a Rails app implementing a game, so it's expected that a player will leave a browser open at the game page. When player Alan takes an action himself, I use AJAX requests to update the game page Alan is viewing to reflect the new state. However, when another player (Bob) takes an action, I don't have (or want) a mechanism to push the change to Alan's view. I would like Alan's page to periodically poll the Rails server to find if there have been any changes since last reload, and to reload the page (either via a whole-page GET or an AJAX call) if not. In order to play nicely with caches and proxies, I'd like to do this by issuing a periodic HTTP HEAD request, get Rails to work out the timestamp of the last change (trivially available from my DB) and respond with that in the Last-Modified header; then have the client-side act on that timestamp. How can I go about doing this?

• How to add event listners / signals to a simple superman class?

  - by Kabumbus

  I can and would love to use boost or std for this. Sorry - I am new to C++. So I created a really simple program like: #include <iostream> #include <string> using namespace std; class superman { public: string punch(){return cout << "superman: I hit the bad guy!" << endl;}; }; int main() { superman clark; clark.punch(); cin.get(); } I want to add an event listner that would tell me when clark punched and cout something like "superman punched!". How to add such event listner and event function to my class?

• Matte or non-widescreen laptop? Do they exist?

  - by Alan Harris-Reid

  Does anyone know of any matte-screen laptops being sold now (15.6 or 17") in the UK? All I can find is the Dell Vostro 3500/3700 range, but there is a premium of around £200 over the price of their Inspiron range (for the 17" model), and I find it hard justifying the extra cost just to have a matte screen. I do not like glossy screens, but it seems the laptop industry has gone the way of "glossy is better - let's get rid of matte". I have read and heard from other developers that as long as there are no strong light sources to reflect off the screen, one can soon get used to a glossy screen, but I am yet to be convinced. I would also be interested if anyone knows of any non 16:9 screen laptops. I find this ratio too wide and not high-enough for the work I do. 16:10 or lower would be better. Any opinions would be appreciated. Alan

• Does laser printer use toner when switched on/off?

  - by Alan Harris-Reid

  I have recently purchased a HP LaserJet M175nw laser printer which goes into sleep-mode after 10 minutes of non-use. I know sleep-mode uses a very small amount of power, but the flashing light on the control panel is driving me nuts! I know I can turn-off the printer via. the on/off button, but when it is turned-on manually, there is some whirring sound which I guess might be the machine warming-up. My question is... Is any toner used during this warm-up (or cleaning) cycle? Am I better-off keeping the printer in sleep mode, or is it ok to turn off manually? TIA Alan

• Excluding certain file types in wget

  - by Alan Spark

  I have been using wget for a while now to mirror files from an ftp server to a local folder. My wget command is as follows: wget -mirror -w 1 -p -nH -P /var/www/ ftp://my-ftp-server However, I just noticed that it is copying over a .listing file for every folder that it visits. So, even if nothing has been changed on the ftp server, a .listing file will always be copied. My understanding is that the .listing file is created when wget opens the ftp session. Is there a way to avoid this? I've tried the -R option (e.g. -R .listing) but this didn't help. See: http://www.gnu.org/software/wget/manual/wget.html#Recursive-Accept_002fReject-Options Thanks, Alan

• How can I persist certificates in Java's cacerts?

  - by Alan Spark

  We need to have a certificate in Java's cacerts keystore for one of our servers that is authenticated by LDAP. We are using Ubuntu server. We have successfully done this by updating the cacerts file in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/security but occasionally a Java update is installed and the cacerts file seems to be getting replaced by a default one that doesn't contain our changes. This doesn't happen very often but it is becoming a bit of a pain when it does happen. Is there a better way of adding things to cacerts so that they don't get lost when a Java update happens? Thanks, Alan

• Syncing Large Directories/Filesystems using USB Drive [closed]

  - by Alan Lue

  Does anyone have a solution for syncing large directories/filesystems using just a USB flash drive (and specifically without using a network connection)? The objective is simply to sync a user directory between two computers. The contents of the user directory could amount to a large quantity of data—say, a quantity larger than could be stored on any single USB drive—but the aggregate size of changes that must be propagated by a single sync could easily fit on a USB drive. As an example, suppose a user directory is already synchronized between a desktop and a laptop computer. Here's a use case: Some changes are made in the user directory on the desktop. We mount a USB drive onto the desktop and copy whatever changes need to be applied to the laptop user directory in order to synchronize the desktop and laptop user directories. We now mount the USB drive onto the laptop and apply the changes. The desktop and laptop user directories are now synchronized. Any ideas? Alan

• Windows XP SP3 dissapearing mapped drives

  - by Alan Spark

  I am running Windows XP Pro SP3 and I've got a few shares on my NAS that are mapped to reconnect automatically. I can access the drives soon after starting windows but after a period of inactivity I get the error "The local device name is already in use". This cannot be remedied until I restart the computer - I've tried disconnecting and re-mapping without success. This was working fine until I recently reinstalled Windows and I'm not sure what is going on. Any help would be greatly appreciated. Thanks, Alan

• format dojo DataGrid header row

  - by Alan Seiden

  I want to assign a background color to my programmatically created Dojo DataGrid's header row. I've tried to override the defaults by adding .dojoxGridHeader or .dojoxGrid-Header to my style sheet, but these have no effect. Is there another way, such as with a Dojo event or property? If my style sheet is the only way to go, am I using the wrong class? Thanks! Alan

• CDN Rerouting on 404 (file not yet in synch with original storage)

  - by Alan Ristic

  Here is the problem. I've setup my app(on EC2) to store uploaded images directly on Amazon S3. I'd like to be able to serve static files(cdn) from my 'home' server so I wrote script that does sync from S3. But there is a window of (at least) one minute in synch. Now I see two solutions on the problem of pics not been available on 'home' server here: 1.I write script on EC2 (where the app resides) to fetch from DB pics that have status of "not-yet-synch", which is default state when user uploads picture. The script then does a ping to picture and if it gets OK response, updates DB from "not-yet-synch" to "synch". 2.Prefered solution would be to let apache (in this case) redirect request for an image if it sees 404 (e.g. doesent find image requested) to S3. This way I wouldn't need script from solution 1. So what approach do you suggest I take in solving this redundancy problem? Or what is practice in production environments? To further clarify; I'd like so serve images first from 'home' server, if that fails serve them from S3. Tnx, Alan

• What makes a game a game vs something else like a puzzle or a toy?

  - by Shannon John Clark

  Famously the Sims and similar games have been described by some designers as Toys and not "really" games. I'm curious if there is a good answer to what makes something a game. For example many companies sell Sudoku games - EA has an iPhone one, IronSudoku offers a great web based one, and there are countless others on most platforms. Many newspapers publish Sudoku puzzles in their print editions and often online. What differentiates a game from a puzzle? (or are all Sudoku "games" misnamed?) I'm not convinced there is a simple or easy answer - but I'd love to be proven wrong. I've seen some definitions and emphasize "rules" as core to something being a game (vs. "real life") but puzzles have rules as well - as do many other things. I'm open to answers that either focus only on computer games (on any platform) or which expand to include games and gameplay across many platforms. Here to I'm not fully convinced the lines are clear - is a "game" of D&D played over a virtual tabletop with computer dice rollers, video & audio chat a computer game or something else? (I'd lean towards something else - but where do you draw that line?)

• Microsoft Terminology: .NET C++ vs. traditional C++

  - by Mike Clark

  I've recently been working with a team that's using both .NET C++ and pre-.NET C++. I fully understand the technical differences between the two technologies. However, I sometimes feel like I'm floundering when it comes to the terminology used to differentiate the two. Example: Say we have two projects: ProjectA contains "C++" code that builds a .NET assembly DLL. ProjectB contains Visual C++ code that builds a traditional native Windows DLL. What is the best way to succinctly and terminologically draw a distinction between the two projects? Again, I'm not asking for an in-depth technical description of the differences between the two technologies. I'm just looking for names and labels. This is how, today, I might try to make the distinction when talking to someone: "ProjectA is a managed .NET C++ project" and "ProjectB is an unmanaged native C++ DLL project." However I am not at all certain that this terminology is ideal, or even correct. Please describe what you feel the ideal language to use in this situation (or similar situations) might be. Feel free to motivate your answer.

• Bash does not remember programs with non 0 exit status in history

  - by Amigable Clark Kant

  I enter a command. It fails. I press arrow up, modify something and enter it again ... hold it right there. It used to work like that. Now it's more like: I enter a command. It fails. I press arrow up, get the last command which didn't fail, likely "ls" or something useless and I type the whole thing again back by hand. What happened? It wasn't always like this. But it's quite some time since this behavior changed, I'll give you that. Some years ago, at least. How do I put some sanity back into my bash prompt?

• How to price code reviews to encourage good behavior?

  - by Chris Clark

  I work for a company that has a hosted .net internet application with many clients. Those clients often want to write customizations for our application. We have APIs to hook into the app, but the customizations themselves are written in .net. This is a shared, secure hosting environment and we have to code review these customizations before we can deploy them in our datacenter to ensure that they don't degrade performance, crash our servers, or open any security vulnerabilities. We charge for these code reviews. The current pricing model is simply a function of the number of lines of code. I think this is a bad idea for a variety of reasons, but primarily because, if we are interested in verifying that the code works as expected, we should be incentivizing good, readable code, not compaction. I would like to propose a pricing model that incorporates some, or all of the following as inputs: Lines of code Cyclomatic complexity Avg function length # of functions Are there any other metrics I should incorporate, or other ideas for how we can reasonably create pricing for code reviews that encourages safe and understandable code?
